This excellent standalone from Nesbø, best known for his Harry Hole series (Police, etc.), centers on Sonny Lofthus (aka the Son), who’s serving a sentence at Oslo’s Staten Maximum Security Prison for two murders to which he confessed but which he did not commit. Sonny began using drugs before his incarceration, after his police officer father, Ab, hanged himself, leaving a note in which Ab confessed to having been a dirty cop. To manipulate Sonny, prison officials, lawyers, and police enable Sonny’s habit. When another inmate, Johannes Halden, who’s dying of cancer, begs for Sonny’s forgiveness after admitting a role in framing Ab and making his murder look like suicide, Sonny stops taking drugs and later escapes from prison with Johannes’s help. He launches a killing spree targeting those he suspects of having destroyed his father—in particular, a gangster known as the Twin, who controls a criminal enterprise encompassing human trafficking, drugs, and money laundering. A love affair between Sonny and Martha Lian, director of a center for drug addicts where Sonny stays, adds another exciting dynamic. Nesbø takes the reader on a chilling ride with many unexpected twists. 150,000-copy announced first printing. Author tour. Agent: Niclas Salomonsson, Salomonsson Agency (Sweden). (May)
